A radon mitigation system is a pipe and a quiet fan that pull radon gas from under your house and vent it safely above the roof. It is a one time cost for a problem that does not come back. The Pennsylvania Department of Environmental Protection says most installations fall between $800 and $1,200, and current national cost guides put the typical job at about $1,000 to $1,700. Where your house lands depends on what is under it and how the pipe reaches the roofline.

What changes the price
Your fixed price comes after a short, free site visit. These are the things that move it.
| Factor | Typical effect on price |
|---|---|
| Foundation type | Basement with a concrete floor $800 to $1,400. Slab on grade, a house built on a concrete slab with no basement, $1,000 to $1,600. Crawlspace, where a heavy plastic sheet is sealed over the dirt and the pipe pulls from under it, $1,500 to $2,800. Mixed foundation, part basement and part crawlspace or slab, $1,800 to $3,000. |
| Larger footprint | Over 2,500 sq ft often needs a second suction point (another hole through the floor for the pipe), which adds $300 to $600. |
| Interior pipe route | Routing through closets and the attic instead of an outside wall adds $300 to $700. |
| Open sump pit | A sump pit is the hole in a basement floor where a pump removes groundwater. A sealed lid you can still see and service through adds $100 to $250. |
| New electrical circuit | A new circuit adds $150 to $400 when there is no outlet near the fan location. |
What the price includes
- The fan, pipe and fittings, sized to your slab and soil.
- Sealing around the pipe where it goes through the floor, along major cracks, at the seam where the floor meets the wall, and over the sump pit.
- A labeled gauge on the pipe, a small U shaped tube of colored liquid that shows at a glance the fan is pulling.
- A follow up radon test after the system is running, with the new level in writing.
- Adjustments at no charge until the follow up test confirms the result.
What a radon test costs
A professional test with a continuous monitor, an electronic meter that records radon every hour for at least two days, usually costs $150 to $300. A store bought kit runs $15 to $30. A kit is a fine first look. For a mitigation decision or a home sale, a monitor gives an hourly record and a report that holds up. See how our radon testing works.
Ways to keep the cost down
- Test before you finish a basement, so the pipe goes in while the walls are open.
- Choose an outside wall route when looks allow. It is usually the lowest cost route.
- Selling a home? The cost is often handled as a credit from the seller at closing, and we work to the deadlines in your sales contract.
Cost questions
How much does radon mitigation cost in Pennsylvania?
Most homes pay $800 to $2,500. The Pennsylvania DEP says most installations fall between $800 and $1,200, and homes with crawlspaces, mixed foundations or pipes run inside the house cost more. Your exact price comes in writing after a free site visit.
How much does a radon system cost to install?
A standard basement system usually runs $800 to $1,500 installed, including the fan, pipe, sealing, gauge and the follow up test. Use the calculator above for a range that fits your house.
How much should radon testing cost?
A professional test with a continuous monitor (an electronic meter that records radon hour by hour) usually costs $150 to $300. A store bought kit costs $15 to $30.
Does homeowners insurance pay for radon mitigation?
Usually not. Insurers treat a radon system as a home improvement rather than sudden damage, so most homeowners pay for it out of pocket. Check your own policy to be sure. If you are buying or selling, the cost is often handled as a credit from the seller at closing or as a repair the seller completes before the sale.
Why do radon mitigation quotes vary so much?
Because the work depends on the foundation, the soil under the slab and the pipe route. Two houses on the same street can need different systems, which is why a fixed price comes after a site visit.
Is the estimate free?
Yes. The site visit and the written price are free, and there is no obligation. Request your free estimate.
Are there costs after installation?
The fan uses about $30 to $100 of electricity a year. Fans usually last well past their five year warranty, and a replacement runs about $250 to $350 installed. Retest every two years or whenever the gauge changes.
